Transformers

IAVNA has been manufacturing its own ALS brand transformers for 40 years to incredibly high standards.  We know that performance under pressure over a long period of time is crucial to airports and we are proud of the quality of our products.

The range has expanded over the years to cover four main types but we can make any special version you may need as well.

The standard AGLST series of airfield ground lighting isolation series transformers covers 30 to 500W.  We then have combined switching models, TSR regulating options and TIPE mains parallel types in stock.

Standard AGLST Range of Airfield Transformers 

Airfield Lighting Systems standard airfield ground lighting isolation series transformers, 30-500W.

ALS manufactures a complete range of Airfield Ground Lighting Series Transformers (AGLSTs), available from 30 to 500 Watts, with a wide combination of input and output currents.

Leads of all length or leads with any combination of plugs and sockets can be supplied along with ‘daisy chains’ of transformers.  Reducing the number of joints and therefore increasing the reliability of the circuit.

All ALS transformers are designed and manufactured to BS EN 61823. This also exceeds the requirements of the FAA AC 150/5345-47.

All AGLSTs come encapsulated in high quality polyurethane resin and are suitable for burial directly into the ground or into pits.

The transformers are fully waterproof.

ALS AGLSTs are resistant to acid and alkaline soils and to chemicals such as oils, fuels and de-icing fluids which are commonly found on airfields.

Combined Switching Transformers

Airfield Lighting Systems combined switching transformers. Using separate transformers with switching units takes up valuable space in transformer pits.

This product is an ideal solution to solve this issue.

The ALS Combined Switching Transformer provides lamp control and power in a single unit, saving space and cost, and minimising connections.

They include a wide range of input and output currents and are available in Fail-On and Fail-Off versions.

The maximum Wattage is 100 Watts. Power and switch circuit isolation is achieved by optical isolation.

Regulating TSR Transformers

A regulating AGLST, or TSR, is an electronically controlled AGLST, designed to provide a different lighting profile to the other luminaries on the same circuit.

All TSRs, are available in the following power ratings: 45W, 65W, 100W, 150W and 200W with input currents of 6.0A, 6.6A and 12A.

The cost is higher than that for standard transformers but is negligible in comparison with the cost of providing a dedicated circuit and CCR.

TIPE Transformers

ALS TIPE’s are constants voltage, or mains powered AGL transformers, and are used to supply a standard light fitting or group of light fittings, typically fed from 220V – 240V 50Hz supply.
